conclusion/ question

1. Define the term salinity

The amount of salt in something

2. If you add salt to a water solution, will a hydrometer float higher or lower in the water?

lower because it was more dense

3. What effect does the addition of salt have on the properties of water?

it makes the salinity level's higher

4. Is it easier to float in the ocean than a swimming pool?

a pool because an ocean has more salt than in a pool

5. Define the term density 

a ratio of the amount mass per unit volume

6. The salinity of seawater is also affected by the temperature of a body of water. Explain how temperature causes differences in the salinity of water

because when it's hot, the molecules of the salt start to move more and multiply

It's all connected

Analysis of Results:

1.   Why do you think there are international laws for dumping waste/trash/chemicals in the ocean, rather than just local laws? Do these laws only need to extend to nearby neighboring countries? Explain. 

    There are international laws for dumping waste into the ocean so that  everyone has the same law to follow. Having this international law they are hoping that everyone around will not violate this law by throwing waste into the ocean. Now more people will follow this law because they would get more trouble having it be an international  law. 

2. What else can be done to protect the oceans from being the repository for waste?

Have larger fine given to the people that get caught. Also they can make a bigger deal about how important the ocean is and try to get peoples attention on how the waste in the ocean can harm our environment.          

3. You have been given a separate question to investigate.  Attach your piece for the display case to this assignment, or submit separately. Remember: colorful, near, accurate, source cited.

Which way the wind blows

Explain what causes Earth's uneven heating, and contrast angled light rays with direct light rays. 

The earth has uneven heating because the earth is on an axis. The earth is tilted so that causes the sun to hit the earths surface unevenly. We did an assignment using a flashlight that referenced how the sun hit the earth. We titled the flashed causing the light from the flashlight to hit the paper having some parts have less light. I enjoyed doing this project because it helped me understand and visualize how the suns light actually hits the earth.

 Describe prevailing global wind patterns. Put perspective into the trade winds, the doldrums, the horse latitudes, and the westerlies by describing actual events. Write an opinion statement about what you learned from the "Global Wind Patterns" activity.

Trade winds are winds that come from the 30 degree line and move into the equator. The doldrum winds are the winds that blow horizontally on the 0 degree line or the equator.      

Loggerhead Island Report

Tori Coberly

1. What special considerations did you have to make for the nesting sea turtle sites located on the barrier island?

• When building our resort we had to make sure our buildings were far away from the sea turtles so that they would not be harmed.  

2. What special considerations had to be made when determining a good site for the proposed fishing pier?

• We wanted to have our fishing pier in a safe and easily accessible area so we put it in the middle of the lagoon. 

3. What could be some of the potential problems that might arise from the proposed golf course? Propose some of the ways in which the impacts can be reduced.

• All the digging in the ground could harm some wildlife. To reduce having a problem like that we could not do so much digging and have a more wildlife safe environment 

4. What are the economic benefits to the community of Loggerhead County if the development was done with the least amount of environmental impact?

• There would be less damage to the wildlife . Which would better the lives of the sea turtles, scrub jay and the other animals that are living on the island. 

5. Describe three ways in which humans negatively impact coastal ecosystems such as the one you are working on with Loggerhead Barrier Island.

• trash and littering 
• pollution from the cars and houses 
• not respect the boundaries that are set to protect wildlife 

6. How can maintaining natural vegetation help us to reduce the damage caused by oceanic events such as hurricanes, tsunami and continued beach erosion?

• You could make a wall in the ocean to prevent the waves from crashing in and damaging the island

7. After listening to the other groups make their presentations, were there any ideas they had you would have used if you had though about it before-hand? You should list at least three different ideas and indicate why their idea is actually better for the environment than yours. 

• We should of spaced our buildings out better. Most groups spread there building out so that no building were all pushed together and close. 
• We should of put our golf course near where the sea turtles are instead of building our Villas there. Having the golf course in place of the Villas, it is a more safe environment for the turtles. They would not be as disturbed because a golf course is a calm place. 
• We could of have our research center farther away from the town and have it be in a more private place.

Maui and Miles Beach were the two sands i was most intrested in. Maui's sand was very well rounded and was very pretty. The sand is very small rocks. The sand is also very smooth. Under the microscope the sand was very very well sorted.
Miles Beach was very different from Maui's sand. The texture was very different. It was small but very rocky and sharp. The sorting was also very different. The sorting was poorly sorted. It was also much smaller than Maui's sand. Also Miles beach is not magnetic but Maui's sand is magnetic.  

Sounding the Sea; A study in Bathymetric Mapping

Research Question: How can the ocean  floor features be measured and mapped  using current acoustical technology? How can ocean floor maps be used in the commercial, military,  and/ or private sector? 

Flat abyssal plain: normally refers to the flat areas of a deep ocean floor 

Underwater sea-mount or guyot: A flat-topped submarine mountain   

Continental shelf: the underwater extension of the continental land mass 

Submarine canyon on the continental shelf: canyon formations that are a result of water flow scouring typically due to river outlet with the canyons normally found on the continental shelf 

Mid-ocean ridge: A series of mountain ranges on the ocean floor, more than 84,000 kilometers (52,000 miles) in length, extending through the North and South Atlantic, the Indian Ocean, and the South Pacific.   

Island arch system:  The volcanic chain parallels the ocean trench and at sea forms a string of volcanic islands


Analysis: 
Our Topography of our surveyed area was mostly within a range of 2 centimeters with a few bumps that were less. By using remote sensing technology is an advantage because it is easier and gives more accurate readings. Using a Y-axis that is stretched out makes the informationn easier to read by having the numbers at a closer range. 

New Questions: 
what is the best way to measure the ocean floor?
which way of measuring the ocean floor is most used by researchers? 

Importance of This Activity: 
the importance of this was to know how the ocean floor is measured. It is good to know how researchers find out the information they share with us. Knowing how they do things helps us understand how the science of it really works
